摘要:
Apparatus for determining the focal plane of invisible laser-therapy radiation in ophthalmological instruments. A visible laser marking beam is split by simple means into four individual beams which share the instrument's optical path with the invisible laser radiation and are combined at the instrument's focal plane to form a single light spot.
